For me, as you can see here: Expected harder training session I took a long time to get up to the right power level. Basically I was trying to find the right gear for a cadence in the right range for me. Overall, it felt like the right amount of effort (I was spent at the end) but I maybe could’ve got a better score if I’d got up to the right level earlier
If you’re able to do the workouts at 100% then I’d stick with the higher score if it were me. Everyone has good days and bad days, though
